Not a fluke. Experienced same issue w/ 2012 SE. Total electrical failure/malfunctioning, including loss of horn, turn signals, and brake lights, accompanied by nonsensical messaging from the main screen. Dealer replacing "body control module"; not yet clear if this will work. A very serious issue potentially, especially if it happens at night (tough to drive at night w/o lights, signals, etc.). Any recurrence of your problems?
